Could you build this?
No Ingesting, parsing, indexing, and maintaining real-time search across 45+ billion Certificate Transparency records requires massive data engineering and distributed database infrastructure.
What it would actually take: The backend needs a continuous distributed ingestion pipeline consuming from dozens of public CT log HTTP endpoints using Apache Kafka or Flink. Storing and indexing tens of billions of certificates requires a massive distributed columnar or search cluster (e.g., ClickHouse or Elasticsearch clusters spanning dozens of high-memory nodes) and specialized expertise in large-scale data engineering.
